When your money is in bank you earn it?

When your money is in a bank, you can earn interest on it, which is a small percentage paid by the bank for allowing them to use your funds. This interest accumulates over time, depending on the type of account you have, such as a savings account or a fixed deposit. Additionally, having money in the bank provides security and liquidity, allowing for easy access to your funds when needed. Overall, it's a way to grow your savings while keeping them safe.
